鱼生长激素是一种小分子量蛋白质,它的主要生理功能是促进鱼类生长发育。我们于2001年5￣11月在厦门明威兴水产有限公司的网箱养殖场进行了添加重组鱼生长激素酵母添加剂对斜带髭鲷和卵形鲳鲹等海水鱼生长的影响实验。实验结果表明:添加剂量为1.0%最合适,实验组比对照组鱼体重分别增重了23.7%和46.0%。对斜带髭鲷鱼肌肉的主要营养成分分析表明:实验组与对照组的蛋白质含量与组成无明显差异,但实验组氨基酸总含量增加(18.2%),尤其是必需氨基酸(21.4%);粗脂肪、水分、灰分和总磷的含量也分别增加了13.0%、6.5%、20.4%和11.2%。
Fish growth hormone is a small molecular weight protein, its main physiological function is to promote fish growth and development. We conducted an experiment on the effects of adding recombinant fish growth hormone yeast additive on the growth of marine fish such as razorbill and oval razor clam from Xiamen Mingweixing Aquaculture Co., Ltd. from May to November in 2001. The experimental results showed that the optimum dosage was 1.0%, the weight of the experimental group was 23.7% and 46.0% higher than that of the control group respectively. Analysis of the main nutritional components of the muscle of the snapdragon snapper showed that there was no significant difference between the experimental group and the control group in protein content and composition, but the total amino acid content in the experimental group increased by 18.2%, especially the essential amino acid (21.4%); The content of fat, moisture, ash and total phosphorus also increased by 13.0%, 6.5%, 20.4% and 11.2% respectively.
